Abstract

Temperature and magnetic field dependence of the Hall effect in the normal and mixed state of fully textured (Hg_0.9Re_0.1)Ba ₂CaCu₂O_6+δ (HgRe-1212) HTSC thin films prepared by laser ablation deposition have been studied. The longitudinal resistivity p_xx and Hall resistivity p_yx of HgRe-1212 superconductor thin films were measured for a wide range of magnetic fields from 125mT to 12T with the field perpendicular to the ab plane and the current in the ab plane. A sign change of the Hall resistivity is observed in fields below 3 T in the region close to the superconducting onset temperature. The temperature dependencies p_xx α T and p_yx α 1/ T have been observed for HgRe-1212 thin films. The Hall angle θ _H relation cotθ_H = αT² + β, remains valid for temperatures T between T_c and 200K. In the mixed state a power-law behavior is observed, where p_yx scales to a power-law function of p_xx: p_yx = Ap_xx ^β with β increasing from 1.0 to 1.7 as the field increases from 1 to 12 T.
